I have heard of small liquid nitrogen tanks and seen pictures of vapor phase liquid nitrogen tanks, but what is a small vapor liquid phase liquid nitrogen tank?
As we all know, small liquid nitrogen tanks are portable containers made of aluminum, and vapor phase tanks are stainless steel tanks for storing large quantities of stem cells and with intelligent monitoring and management systems, so what are small vapor-liquid phase liquid nitrogen tanks?
We can think of it as a combination of a small vapor phase tank and a conventional liquid nitrogen tank! Why do you say that?
Look at the exterior, as shown below, it looks similar to the YDS series open top liquid nitrogen tanks, but with an intelligent display!
Looking at the internal structure, there is both space for liquid nitrogen storage and a separate area for sample storage, similar to a vapor phase tank.
But if you look at the material, you will find that the small vapor-liquid phase liquid nitrogen tank is completely different from the material used in the vapor phase tank, which is instead made of YDS series aluminum alloy or aviation aluminum alloy, which is strong, but lighter and more resistant to corrosion.
Then look at the sample storage method, the small vapor liquid phase liquid nitrogen container supports dual mode, both liquid phase storage and liquid nitrogen samples can be stored separately, using vaporized liquid nitrogen to preserve samples, which is the main origin of its name! Is it particularly similar to the YDD series vapor phase tank? Only the model is smaller, non-large laboratory can also be used.
If you want to preserve a larger number of cell-based samples in vapor phase, but feel that a vapor phase liquid nitrogen tank is too large an investment or a bit wasteful for the number of samples you have, then use a small vapor phase liquid nitrogen tank!
